1007 ! Firmware Fault on %4 All PICs: A 'run-time' error was detected
in the PIC firmware. For example, a timer
is turned off at a point where the firmware
expects it to be on. The firmware will at‐
tempt to recover. Usually an additional
specific flag will be set to provide more
information about the cause of the fault.
Contact Customer Support.
1008 ! EEPROM Bad Value on %4 All PICs: A value read from EEPROM is
out of range or invalid. This may happen
if a board’s EEPROM was incorrectly in‐
itialized during manufacturing.
Cycle power.
If the error repeats, replace the module.
1009 ! Local I2C error on %4 All PICs: A fatal error was detected while
accessing the internal, on-board I2C bus
(not the private bus between a SNE and
a DPM). The communication with the on-
board EEPROM or the LM75 (on board
temperature sensor) is not working nor‐
mally.
Cycle power.
If the error repeats, replace the module.
1010 ! Fatal error on %4 All PICs: An error or an invalid operation‐
al condition was detected by the PIC firm‐
ware. The board is shut down to a failsafe
mode.
Contact Customer Support.
1041 ? AO Out Of Range on %4 All PICs: An AO was set to a value out‐
side of the allowed range. The value was
clipped to the allowed range.
For example, an EPC has a 0 to 100 psi
nominal range for the pressure setpoint.
An attempt to set the setpoint to 150 psi
results in an "AO out of range" and the
setpoint is clipped to remain within the
allowed range (100 psi).
Locate the problematic AO and change
the AO value to a value within the prop‐
er range.
1042 ? Invalid Group Channel on
%4
All PICs: The hardware I/O channel(s)
requested does not exist on the module.
Check the 'Sys Hardware' table for in‐
valid entries.
Check that only detector channels are
specified in the detector I/O table.
Check that only EPC are defined in the
pressure controller table.
Check that only temperature controllers
are defined in the temperature control‐
ler table.
1043 ? Invalid EEPROM Address
on %4
All PICs: The on-board EEPROM ad‐
dresses requested do not exist or cannot
be accessed within a single command.
Report to Customer Support for further
investigation.
